UCSD academic calendar 2026-2027 key dates include enrollment periods, fee deadlines, class start/end dates, finals weeks, and grading timelines.

The University of California, San Diego (UCSD) follows a quarter system, dividing the academic year into four quarters: Fall, Winter, Spring, and Summer.

While most students enroll in classes during the Fall, Winter, and Spring quarters, the Summer Session offers additional opportunities for those looking to accelerate their studies or catch up on credits.

Each quarter is just 10 weeks long, making the pace fast and the schedule intensive; every week counts.

The Fall 2026 Quarter at UCSD includes 49 days of instruction. The Winter 2027 Quarter has 48 instructional days, while the Spring 2027 Quarter also consists of 49 days of instruction.
